BACKGROUND: Choledochal cysts are associated with ductal strictures, stone formation, cholangitis, rupture, secondary biliary cirrhosis and increased incidence of cholangiocarcinoma. The surgical approach to choledochal cysts has evolved from the cyst-enterostomy to a complete excision with more recent use of minimally invasive approaches. We report a complete minimally invasive approach to a Type 1 choledochal cyst and summarize the literature containing large case series of similar approaches...

Most cystic lesions of the liver are found incidentally in imaging studies because they are not symptomatic, and generally do not require treatment. Rarely, however, symptomatic hepatic cysts may develop complications and require treatment. Here, we describe a case of a 77-year-old woman who developed biliary obstruction with abdominal pain due to compression of the bile duct by a simple hepatic cyst. We confirmed the diagnosis based on symptoms and imaging studies. The patient'ssymptoms improved after simple cyst ablation by sclerotherapy...

Choledochal cysts involving the cystic duct are extremely rare, and are usually associated with cystic dilatations of the extrahepatic biliary tract. We describe a patient who presented with jaundice and was found to have a dilatation of the common bile duct on computed tomographic imaging, consistent with a choledochal cyst. He underwent a laparoscopic-converted-to-open cholecystectomy with excision of the choledochal cyst which was found to involve the cystic duct. Choledochal cysts involving the cystic duct are notably missing from the Todani classification...

BACKGROUND/AIMS: Genetic defects in Polycystins -1 or -2 (PC1 or PC2) cause polycystic liver disease associated with ADPKD (PLD-ADPKD). Progressive cyst growth is sustained by a cAMP-dependent Ras/ERK/HIFα pathway leading to increased autocrine/paracrine VEGF-A signalling. In PC2-defective cholangiocytes, store-operated Ca(2+) entry (SOCE), intracellular and endoplasmic reticulum [Ca(2+)]ER levels are reduced, while cAMP production in response to [Ca(2+)]ER depletion is increased. We hypothesized that in PC2-defective cells, in response to [Ca(2+)]ER depletion, the Ca(2+)-inhibitable adenylyl-cyclases AC5 or AC6 are activated by the ER chaperon STIM1 resulting in cAMP/PKA-dependent Ras/ERK/HIFα pathway activation...

: Choledochal cyst is a rare pathological condition, which represents 1% of benign diseases of the biliary tract. It is seen with significant frequency in childhood, with a higher prevalence in females, and a greater diagnostic incidence in Asia. Diagnosis is primarily based on clinical suspicion. Its symptoms are variable, and its treatment, depending on the type, is surgical. CASE REPORT: a male patient, 46 years old, with clinical symptoms of acute pancreatitis as a complication of a choledochal cyst Todani type II is diagnosed during his hospital stay with cholangial magnetic resonance...

BACKGROUND: Choledochal cyst is a congenital dilatation of the biliary tree. It may affect only the extrahepatic bile duct (type I, II and III), intrahepatic (type V) or both (type IVa). Vater first described choledochal cyst in 1723. Open excision was the standard procedure made a great impact in the treatment but since 1995 Farello et al. first reported laparoscopic choledochal cyst excision and this has been used worldwide. CASE REPORT: Female, 17 years old, past medical history two years ago a laparoscopic cholecystectomy for gallbladders...

Introduction. Gallbladder volvulus is a rare, potentially fatal condition unless diagnosed and treated early. Choledochal cysts are rare congenital malformations of the biliary tree predisposing to different pathologies and posing the risk of degradation into cholangiocarcinoma and gallbladder cancer. Dealing with both diseases at once has not been published yet in the literature. Presentation of Case. We report a case of gallbladder volvulus in an elderly female who happened to have a concomitant type I choledochal cyst...

Unlike its family member p53, TP63 is rarely mutated in human cancer. However, ΔNp63α protein levels are often elevated in tumors of epithelial origin, such as squamous cell carcinoma and cholangiocarcinoma. To study the oncogenic properties of ΔNp63α in vivo, we generated transgenic mice overexpressing ΔNp63α from the Rosa26 locus promoter controlled by keratin 5-Cre. We found that these mice spontaneously develop epidermal cysts and ectopic ΔNp63α expression in the bile duct epithelium that leads to dilatation of the intrahepatic biliary ducts, to hepatic cyst formation and bile duct adenoma...

Mucinous cystic neoplasms (MCNs) can occur in the pancreas and liver. Classically, these cystic lesions are lined by columnar mucinous epithelium with underlying ovarian-type stroma. It has been proposed that cysts with ovarian-type stroma and nonmucinous epithelium be considered separate entities in both the pancreas and liver. Using a series of 104 pancreatic and 32 hepatic cases, we aimed to further characterize the epithelium present in MCNs. Mucinous epithelium was defined as pancreatic intraepithelial neoplasia-like columnar cells with pale pink/clear apical mucin...

BACKGROUND: Hepatobiliary stone disease is one of the most common surgical conditions worldwide. There are multiple causative agents responsible for the formation of hepatobiliary stones, and bacterial infection is one of them. The presence of Helicobacter DNA species has been investigated in the biliary epithelium of patients with biliary diseases. However, conflicting results have been observed that may have been due to the small number of subjects studied, difficulty in obtaining a healthy control group, absence of controlling for confounding factors, or ethical and regional differences among populations...

BACKGROUND: Pancreaticobiliary maljunctions (PBMs) are congenital anomalies of the junction between pancreatic and bile ducts, frequently associated with bile duct cyst (BDC). BDC is congenital biliary tree diseases that are characterized by distinctive dilatation types of the extra- and/or intrahepatic bile ducts. Todani's types I and IVa, in which dilatation involves principally the main bile duct, are the most frequent. PBM induces pancreatic juice reflux into the biliary tract that is supposed to be one of the main factors of biliary cancer degeneration, although the diagnostic criteria of PBM that can be either morphological and/or functional are not well defined especially in Western series...

BACKGROUND: Tumour markers are substances produced by the tumour itself, or by the host in response to a tumour. These markers could be measured either in the blood or in body secretions. One of the most common tumour markers used in gastrointestinal diseases is Ca 19-9. It is the marker most used for pancreatic cancer, but can be elevated in many benign processes. Thus, it is not a specific marker. CLINICAL CASE: The case is presented of a male patient with 4 years of moderate abdominal pain, weight loss, and persistent elevation of Ca 19-9...

OBJECTIVE: Surgery and percutaneous aspiration-injection-re-aspiration (PAIR) are widely accepted treatment modalities for hepatic hydatid cysts. Endoscopic retrograde cholangiopancreaticography (ERCP) acts as a minimally invasive rescue method for the biliary complications of both the hydatid cysts and treatment modalities. The aim of this study was to identify the role of different treatment modalities in the obliteration of hydatid cysts. METHODS: Patients treated for hydatid cysts between January 2009 and December 2013 were evaluated in the study...

The neurohypophysial hormone arginine vasopressin (AVP) acts by three distinct receptor subtypes: V1a, V1b, and V2. In the liver, AVP is involved in ureogenesis, glycogenolysis, neoglucogenesis and regeneration. No data exist about the presence of AVP in the biliary epithelium. Cholangiocytes are the target cells in a number of animal models of cholestasis, including bile duct ligation (BDL), and in several human pathologies, such as polycystic liver disease characterized by the presence of cysts that bud from the biliary epithelium...
